The Lowdown

Alright folks, Rusty here. Let’s be straight with you: the next 16 days at Kennebunk Beach are a tough one. We’re looking at a long stretch of mostly flat, weak surf that’s really just not gonna get you out of bed. There’s a dry spell from now all the way through most of the period, with only a couple of moments that might just about get you on the water.

The overall picture is dominated by tiny, weak swell. The combined wave energy never really gets out of the low double digits for most of the run, and the only time it even cracks the 3-digit mark is on Sunday the 6th with a weak 112, and then again on Thursday the 10th with a modest 104. That tells you everything – it’s anemic.

Water temps are about what you’d expect for this time of year, no huge anomaly to report here at Kennebunk.

Looking at the first real pulse: Sunday, September 6th. The morning offers the best of a bad bunch. You’re looking at a 3ft swell out of the ENE, with a 7-second period, and a light cross-off breeze from the NNE at 6 mph. The wave energy is still weak (112), and the swell direction is a little off the optimum, but the wind keeps things clean. Expect mushy, small lines, not much push. This is for the intermediate crew – beginners will find it tiny enough to try, but the lack of power makes it frustrating.

From there, we enter a real desert. Monday the 7th through to Saturday the 13th is a depressing run of knee-high slop and flatness. Swell drops to 0.6ft-0.9ft, periods are all over the shop, and the energy falls off a cliff. The mornings of Wednesday the 9th and Thursday the 10th have onshore or cross-onshore winds, making it a choppy mess. Not worth the drive.

Now, a small lift on Sunday, September 13th. The afternoon brings the largest swell of the whole outlook at 4ft out of the S, but the period is a short 5 seconds, and it’s a moderate cross-onshore wind from the S at 15 mph. The energy (98) is still weak, and the wind will chop it up. This is really only for the most desperate, and honestly, with the cross-onshore breeze and short period, it’s looking more interesting for kite surfing than paddle surfing.

Finally, on Saturday, September 20th, the morning offers a clean 3ft from the S with a 5-second period. The 9 mph offshore from the NE will keep the faces clean, but again, the period is short and the energy is low (78). A tiny, clean wave for a log on a calm morning.

Look, there’s no standout here. The best of a terrible hand is probably the Sunday morning, September 6th. It’s clean, it’s the biggest early swell, and it’s the only time the energy even hints at being rideable before the wind ruins it. But don’t expect any magic. Keep the board in the car and check the cams.

Rusty.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
